The hard part of content is not writing, it is knowing what is worth writing about this week. That answer is in your sales calls, not in a brainstorm.
A concept that arrives with fourteen prospects asked this in the last six weeks is a different proposition from a concept that arrives as an idea. It survives the review meeting, it gets written with more conviction, and it is more likely to be about something the audience actually cares about.
Concepts with no reason behind them are the ones that become posts nobody engages with, and nobody can say afterwards why the topic was chosen.
Content programs repeat themselves constantly, because the good topics keep feeling like good topics. Reading what was published recently before generating anything is a cheap step that prevents the most visible failure mode there is.
On a feed the image is read before the words. A concept that specifies only the text leaves the most important half to whoever makes the graphic, working from a caption. Both are decided at concept stage.
Skills compound. These are the ones we usually install alongside it.
